Abstract: In wireless ad hoc networks, Ad-hoc On-Demand Distance Vector (AODV) routing protocol uses static value for |Active-Route-Timeout| (ART) which indicates the lifetime of an active route in the routing table. As accurate and dynamic ART is more suitable than static one, the fuzzy logic system is used here to obtain adaptive ART (fuzzy ART) values. Considering various parameters on fuzzy ART, three design methods are proposed, namely: fuzzy-SKP, fuzzy-Power and fuzzy-Comb. Analysis shows that the proposed methods are able to optimise ART quite efficiently and superior to the conventional method with respect to routing overhead and average end-to-end delay.

Keywords: ad hoc networks; AODV routing; adaptive route timeout; fuzzy route lifetime; wireless networks; ad-hoc on-demand distance vector; active routes; fuzzy logic; fuzzy ART.
